block_user/4 and block_user/5 blocks the user
User from the directory Dir for a specified
amount of time.

unblock_user(User, Port) -> true | {error, Reason}

unblock_user(User, Address, Port) -> true | {error, Reason}

unblock_user(User, Port, Dir) -> true | {error, Reason}

unblock_user(User, Address, Port, Dir) -> true | {error, Reason}

User = string()

Port = integer()

Address = {A,B,C,D} | string() | undefined

Dir = string()

Reason = term()

unblock_user/2, unblock_user/3 and
unblock_user/4 removes the user User from
the list of blocked users for the Port (and Dir) specified.

The SecurityCallbackModule

The SecurityCallbackModule is a user written module that can receive
events from the mod_security Erlang Webserver API module.
This module only exports the function(s),
event/4,5,
which are described below.

event(What, Port, Dir, Data) -> ignored

event(What, Address, Port, Dir, Data) -> ignored

What = atom()

Port = integer()

Address = {A,B,C,D} | string() <v>Dir = string()

Data = [Info]

Info = {Name, Value}

event/4 or event/4 is called whenever an event
occurs in the mod_security Erlang Webserver API module (event/4 is
called if Address is undefined and event/5 otherwise).
The What argument specifies the type of event that has
occurred, and should be one of the following reasons;
auth_fail (a failed user authentication),
user_block (a user is being blocked from access) or
user_unblock (a user is being removed from the block list).

Note!

Note that the user_unblock event is not triggered when
a user is removed from the block list explicitly using the
unblock_user function.
